It doesn't, but I'd like to find a better way to specify additional padding, especially because we've already got a hard-coded hack to add 8MiB to the rootfs. We also add an additional 50% in the calculation. I don't like hacks upon hacks. ;) I suppose I can justify some heuristics to account for the overhead of ext4 (although I'd like to remove the in-source hard-coding), but maybe it makes better sense to define the fudge factors in the gadget.yaml? This would mean adding something like a rootfs-size (and bootfs-size?) option to the volume subkeys. I've opened this feature request bug: https://bugs.launchpad.net/ubuntu-image/+bug/1632085 Please comment here with any additional information or suggestions. Cheers, -Barry
